3 1. Overview FLOALARM is especially conceived to monitor alarm conditions in compressed gas storages and supply pipelines. Three types are available: K4 with four inputs, K8 with eight inputs and K12 with twelve inputs. All alarm inputs are compatible with popular switch sensors and inductive proximity sensors type NAMUR. The alarm status is testified by the visual and acoustic signals. Visual signals include 4 (8 or 12) red LEDs associated to each alarm input. Two green LEDs: one green LED (Power) to indicate that the device is powered and one green LED (OK) to indicate that there are no alarm conditions. Blinking status of red LED testifies that the corresponding alarm input is active and this alarm condition is still unacknowledged. Fixed lighted status of red LED testifies that the corresponding alarm input is active and this alarm condition was already acknowledged. Acoustic alarm signal indicates one or more unacknowledged alarm conditions. All current unacknowledged alarm conditions become acknowledged and the acoustic signal is switched off by pushing CANCEL HOOTER button. The TEST button starts the standard test of all signaling devices and programming check cycle. A relay output is available to drive an additional hooter or an external alarm indicator. All programming functions can be set and modified by two buttons on the back of the frontal part of the alarm device. 2. Set-UP WARNING: For safety reasons, the qualified operators must only carry out the installation in accordance with this instruction manual. The manufacturer rejects any responsibility for accidents or damages due to negligence of these instructions Connecting Power Supply Use 1.5 mm 2 section cables. Put a 2 A bipolar security interrupter on the power supply line Connecting Inputs Connect each sensor using bipolar mm 2 section cable. Shielded cables with shields connected to earth are suggested, but not mandatory Connecting Relay Output Use 0.5 to 1.5 mm 2 section cables, in function of switching current and line length First Power-UP At the first power-up, all the inputs are set normally closed (NC), the green LEDs of OK and POWER must be on and all the red LEDs are off; the ringtone is not active. 3 GES_K12_0915.docx

7 4. Configuration of device To configure the device, it is necessary to enter in the configuration mode. CONFIGURATION MODE To enter in the configuration mode, follow these steps: - Open the box removing the screws under the cover strips. - Push for 5 seconds one of the yellow push button behind the front panel. The green LED of POWER will start to blink. SELECTION OF THE INPUT To select the input that must be configured, follow these steps: - Push the TEST button. Scroll the inputs; the input selected is indicated by the red LED. - Push the HUPE AUS/CANCEL HOOTER button. The red LED start to blink. CONFIGURATION OF THE INPUT SELECTED To configure the parameters of the inputs selected, check the LEDs on the bottom PCB on the device (their locations are indicated in the connection diagram of the previous page). - Push the TEST button to scroll the LEDs - Push the HUPE AUS/CANCEL HOOTER to choose the status of the LED (blinking or fixed) Meaning of the LED status LED Parameter Blinking Fixed LED 1 LED behavior Blinking Fixed LED 2 Contact configuration Normally Open Normally Closed LED 3 Ringtone configuration Active Disabled LED 4 Relay configuration Active Disabled LED 5 Exit LED - Scroll till the LED 5 - Push HOPE AUS/CANCEL HOOTER to exit from the configuration of the input. The RED led correspondent return fixed. 7 GES_K12_0915.docx

8 RINGTONE SOUND LEVEL To choose the sound level of the ringtone, move the SWITCH on the bottom PCB (in the diagram of previous page, it is indicated with SWITCH). LEFT position: HIGH sound level. RIGHT position: LOW sound level. DEFAULT PARAMETERS To load the default parameters, follow these steps: - Push the two yellow button behind the front panel. All LEDs start to blink. - Push the TEST button. Start a consecutive activation of all LEDs. Default parameters (same for each inputs): - LED behavior: Blinking. - Contact configuration: Normally Closed. - Ringtone configuration: Active. - Relay configuration: Active. EXIT FROM THE CONFIGURATION MODE To exit from the configuration mode, follow these steps: - Scroll the input until arrive to the POWER LED. - Push HUPE AUS/CANCEL HOOTER - The 5 LEDs on the bottom PCB will blink in sequence and all LEDs on the front panel lights. - After that, the configuration is set and the device is ready to work. 8 GES_K12_0915.docx

9 5. Working Alarm management The standard alarm sequence includes three steps: Case 1: acknowledgement before the end of the alarm event 1. Start of alarm event: input switches from normal to alarm condition. Buzzer switches on and the corresponding alarm LED becomes blinking or fixed (depending to the setting), indicating an unacknowledged alarm status. 2. Alarm acknowledgements: user pushes CANCEL HOOTER button. Buzzer stops and alarm LED switches from blinking to fixed (if in the setting it was configured to blink), indicating an acknowledged alarm status. 3. End of alarm event: input switches from alarm to normal condition. Alarm LED switches from active to off. Case 2: acknowledgement after the end of the alarm event 1. Start of alarm event: input switches from normal to alarm condition. Buzzer switches on and the corresponding alarm LED becomes blinking or fixed (depending to the setting), indicating an unacknowledged alarm status. 2. End of alarm event: input switches from alarm to normal condition. Same signals continue, system remains in previous alarm status. 3. Alarm acknowledgement: user pushes CANCEL HOOTER button. Buzzer stops and alarm LED turns off. The alarm management is with memory ; namely, if the end of the alarm event occurs before the acknowledgement, the equipment remains in unacknowledged alarm status, until the acknowledgement. Acknowledgement operation is effective over all the current alarms. 9 GES_K12_0915.docx
